IMPROVEMENT IN PAPER BOXES.

Specification forming part of Letters Patent No. 164,601, dated J une15, 1875; application filed May 20, 1875.

To all whom it may concern:

Be it known that I, EDWARD DE F. SHEL- TON, of Birmingham, in the countyof New Haven and State of Connecticut, have invented a new Improvementin Paper Box; and I do hereby declare the following, when taken inconnection with the accompanying drawings and the letters of referencemarked thereon, to be a full, clear, and exact description of the same,and which said drawings constitute part of this specification, andrepresent, in-- Figure 1, the blank as prepared for folding. Figs. 2, 3,4. illustrate the peculiar folds which constitute the improvement.

This invention relates to an improvement in the paper box for whichLetters Patent were granted to me, dated December 22, 1874, the objectof the improvement being a more perfect locking of the box than can bein that construction; but such locking is applicable to boxes of otherconstruction.

A is the principal side B,the opposite side C D, the two sides between.B is folded over A, and the lap E turned down upon and secured to D. Fis the bottom or lower end, on each side of which is a flap, G. H is anextension from F, and forms the inner or lining side for B. On each sideare two wings, I I, to form the lining for the two sides C D. Thesethree sides H I I and the two flaps G G are turned within the principalparts of the box, as in my previous construction, the tongue Lprojecting above, as seen in Figs. 2 and 3. Upon the opposite end of Ais a tongue or projection, N, longer than the width of the box by somuch as the part P. The

sides C and D are each formed with a flap, R, which turns down over thebox when folded as in Fig. 2. The end N is then turned down and the tipP tucked into the box, inside the tongue L, as seen in Fig. 3. The end Nis slit, as at a. After the end N has been folded down and tucked in, asin Fig. 3, then the tongue L is passed through the slit a, beneath theend N, as seen at Fig. 4, and the box is secure.

By this construction the tuck P is locked in place by the tuck L, whichoverlaps the angle between the tuck P and the end N, and prevents allpossibility of the accidental displacement or opening of the closed end.

This, while specially adapted to the box I have described, is alikeapplicable to boxes of other construction, it only being essential thatthe two opposite sides should be constructed so that the end of one willtuck directly into the box, and the other into the first.

I therefore do not wish to be understood as confining this lockingdevice to this particular box.

I claim In paper boxes, the combination of the folding slitted end N andtuck P upon the extreme of one side, combined with the tuck L upon theextreme of theopposite side, to overlap the tuck P and enter the slit inthe end N, substantially as described.
